采用电解质渗漏法测定八角根部直接热伤害，角叶冬青CV. Burfordii和Juniperus chinensis L. CV.帕森尼人发现电解质渗漏百分比与温度处理之间呈S形关系。在50.5 ± 0.5°、48.5 ± 0.5°和46.5 ± 0.5°C下暴露20分钟，I. anisatum、J.chinensis和I. cornuta，分别。
Electrolyte leakage was used to measure direct heat injury to roots of Illicium anisatum L., Ilex cornuta L. cv. Burfordii and Juniperus chinensis L. cv. Parsonii. A sigmoidal relationship was found between percent electrolyte leakage and temperature treatment. About 50% electrolyte leakage was realized from a 20 minute exposure of roots to 50.5 ± 0.5°, 48.5 ± 0.5° and 46.5 ± 0.5°C for I. anisatum, J. chinensis, and I. cornuta, respectively.
